Mixed 5.1 and 2ch stereo with HDMI Matrix
Hello everyone, I’m back with another query to see if my assumptions are correct.
I’m going to have a setup with a 8x6 4K HDMI matrix for video distribution, however, there are only 2 zones that I want 5.1 audio in. My understanding is that hdbaset matrix technology works on the lowest common denominator, therefore, if I connect zones that want 5.1 and 2 ch, it will only output 2 ch.
After doing some reading, I understand that some components (input devices) can output audio via HDMI and optical simultaneously. Therefore, what I aim to do is the following.
Connect components to matrix, and set those that I want 5.1 from to output via optical. Probably 4 of 6 input devices.
Then run optical to a 4x2 ir controlled optical switch. Thus, the 2 zones I want 5.1 to, will receive multi-channel audio, while other zones will get standard 2 ch straight from the hdbaset connection on the HDMI matrix.
As the run for 1 is the 5.1 zones is quite long, I’ll probably have to use baluns over CAT to get it to the location.
Is this a workable design?
I know that scalers are available for the HDMI matrix I’m looking at, but that would require 4 scalers to downmix the 5.1 in 4 zones. And they’re not that cheap.
Any info would be really helpful.
